This document describes how to install the Natural Optimizer Compiler (also referred to as NOC) in the various environments supported.
Below is information on:
The installation of Software AG products is performed by installation jobs. These jobs are either created manually or generated by Software AG's System Maintenance Aid (SMA).
For each step of the installation procedure described below, the job number of a job performing the corresponding task is indicated. This job number refers to an installation job generated by SMA.
For information on using SMA for the installation process, refer to the System Maintenance Aid documentation.
Products and versions are specified in the sections Natural and Other Software AG Products and Operating/Teleprocessing Systems Required in the current Natural Release Notes.
The installation tape contains the dataset listed in the table below.
| Dataset Name | Contents |
|---|---|
NOCvrs.LOAD |
This dataset contains the Natural Optimizer Compiler load modules. |
The notation vrs in dataset
names represents the version, release and system maintenance level number of
the product.
For a detailed description of the installation tape refer to the Report of Tape Creation which accompanies the tape.
The space the dataset requires on disk is shown in the Report of Tape Creation.
The installation tape contains the following dataset:
| Dataset Name | Contents |
|---|---|
NOCvrs.LIBR |
LIBR backup file.
|
The notation vrs in dataset
names represents the version, release and system maintenance level number of
the product.
The installation tape contains the following dataset:
| Dataset Name | Contents |
|---|---|
NOCvrs.MOD |
Optimizer Compiler module library. |
The notation vrs in dataset
names represents the version, release and system maintenance level number of
the product.
For a detailed description of the installation tape refer to the Report of Tape Creation which accompanies the tape.
The space the dataset requires on disk is shown in the Report of Tape Creation.
The installation tape contains the dataset listed in the table below.
| Dataset Name | Contents |
|---|---|
NOCvrs.TAPE |
This dataset contains the Natural Optimizer Compiler load module. |
The notation vrs in dataset
names represents the version, release and system maintenance level number of
the product.
For a detailed description of the installation tape refer to the Report of Tape Creation which accompanies the tape.
The space the dataset requires on disk is shown in the Report of Tape Creation.
To copy the tape contents to disk
Position the tape for the TAPE LOAD
command by calculating the number of tape marks as follows:
If the sequence number of
NOCnnn.TAPE, as shown by the
Report of Tape Creation, is n,
you must position over 3n- 2 tape marks (that is,
FSF 1 for the first dataset, FSF 4 for the second,
etc.)
Access the disk that is to contain the Natural installation files as Disk A.
Ask the system operator to attach a tape drive to your virtual
machine at the address X'181' and mount the Natural Optimizer
Compiler installation tape.
When the tape has been attached, enter the following CMS command:
TAPE REW
Position the tape by entering the CMS command:
TAPE FSF n
where n is the number of tape marks and is calculated as described above (3n- 2).
Load the Natural Optimizer Compiler/CMS installation material by entering the CMS command:
TAPE LOAD * * A
Keep the tape drive attached to your virtual machine, because the tape is needed later in the installation procedure.
Activate the Natural Optimizer Compiler by adding the following macro
to your Natural parameter module (NATPARM):
NTOPT ON
Assemble and link the parameter module.
Adapt the link steps for Natural.
z/OS
Add the following INCLUDE instruction to all links of
the Natural nuclei (if you are using a shared nucleus, then include this
statement in the link of the shared part):
INCLUDE NOCLIB(NOCNUC)
Add the corresponding DD statement:
//NOCLIB DD DSN=NOCvrs.LOAD,DISP=SHR
z/VSE
Add the following INCLUDE instruction and the
corresponding sublibrary for the Natural Optimizer Compiler in the search chain
for the linkage editor:
INCLUDE NOCNUC
BS2000/OSD
Add the following INCLUDE instruction to the element
LNATSHAR in NATvrs.JOBS:
INCLUDE NOCNUC,NOCvrs.MOD
Relink your Natural nucleus as described in Link the Natural Nucleus in Installing Natural under BS2000/OSD in the Natural Installation documentation.
VM/CMS
The list of text files to be included in the Natural module or DCSS
is contained in REXX program NAT$LOAD EXEC (variable
LOADLIST). To customize your Natural system, modify this
EXEC with XEDIT by changing the LOADLIST
as required.
Add the following INCLUDE instruction to the program
NAT$LOAD EXEC:
LOADLIST = LOADLIST 'NOCNUC'
Relink your Natural nucleus with the procedure
NATBLDM.
Recatalog an existing program or write a new program and then catalog it.
Check the directory information for the program you have just
cataloged, by using the LIST system command:
LIST DIR
object-name
The directory information for the specified object will be displayed, showing the size of the machine code at the bottom of the screen.
